Title: Electronic control unit
Inventor: YAMAKITA HIROSHI
IPC: F02D45/00
Filed: 1992-04-23
Abstract: PURPOSE:To greatly reduce a processing load relating to an arithmetic unit by independently executing various processes relating to interruption of input/ output. CONSTITUTION:In the case of an on-vehicle electronic control unit 1 of this practical example, a detection signal from the first sensor 17, serving as a detecting means, is converted into a specified detection data in accordance with a LAN protocol by an input/output ECU5, serving as an input processing means, and stored. Arithmetic ECUs 7 to 11, serving as control quantity arithmetic means, receiving the detection data through a LAN circuit 3 serving as a communication line, are only required to calculate a control quantity of a control objective equipment based on the received detection data. Further, a control quantity data as the arithmetic result is stored by the input/output ECU5 serving as an output processing means and converted into a specified control signal to feed it to the control objective equipment. That is, in the arithmetic ECUs 7 to 11, a processing load is greatly reduced by obviating the necessity for executing an input/output process relating to interruption or the like from the first sensor 17.

Title: Controlling method of inverter
Inventor: MATSUMOTO KEIJI
IPC: H02P3/18
Filed: 1985-05-17
Abstract: PURPOSE:To obtain the maximum brake torque by controlling an inverter so as to automatically decide a decelerating pattern matched to a load. CONSTITUTION:When a switch 8 is opened, the output of an operational amplifier 10 starts decreasing at the time constant determined by the circuit constants, and when the output voltage of a voltage detector 16 becomes the voltage of a reference voltage source 17, the amplifier 10 stop integrating by the output of a comparator 18 to hold the output at that time. Accordingly, the decrease in the output frequency of the inverter stops, the same frequency is maintained to hold the rotating speed of the motor constant. When the output voltage of the detector 16 decreases and it becomes a voltage lower than the source 17, the amplifier 10 again starts integrating, and a motor is decelerated. Such an operation is repeated to eventually stop the motor.

Title: Method for adjusting image density of electrophotograph
Inventor: OOTSUKA YASUMASA
IPC: G03G15/06
Filed: 1984-05-24
Abstract: PURPOSE:To obtain extremely good image quality by changing synchronously the electrification quantity of electrification and the voltage quantity of a bias voltage thereby adjusting the density of the sensible image. CONSTITUTION:Interlocked variable resistors 21, 22 have commonly a shaft 23 and the resistance values thereof can be changed by the revolution of the shaft 23. The resistor 21 is used to regulate the output voltage of a developing bias power source 25. The voltage output terminal DB of the power source 25 is connected to a developing sleeve 9. The resistor 22 is used to regulate the output voltage of a grid bias power source 26. The voltage output terminal GB of the power source 26 is connected to a grid 20. The negative output voltage from the power source 25 and the negative output voltage from the power source 26 increase when the shaft 23 is rotated clockwise in the case of increasing the image density. The primary electrification voltage increases in negative when the negative voltage of the grid bias increases. The potential in the dark part increases accordingly. Since the developing bias potential is high as well, the developing contrast voltage increases and therefore the image density increases. The shaft 23 is conversely rotated counterclockwise in the case of decreasing the image density.

By using this transformation table 2, the next (m) bit information following to the current m-bit information is transformed into the transformed data of (n) bits. Thus, the dispersion of stored code weight values can be reduced, the DC component can be decreased, and the error rate can be reduced.

Abstract: PURPOSE: To obtain the phase shift output featuring a large output level by controlling the output phase through variation of the emitter currnet of the 1st and 2nd transistors and at the same time by compounding the voltage or current via the compounding circuit.  
     CONSTITUTION: With supply of subcarrier signal V sent from signal source 10 to transistors Q 1  and Q 2 , signal voltage -V and V featuring the opposite phase to each other are caused at the collectors of the transistors. And voltage V 1  and V 2  are obtained at the emitters of transistors Q 3  and Q 4 ; while voltage -V 1  and -V 2  are obtained at the collectors of transistors Q 7  and Q 8  respectively. At the same time voltage -V/2 and V/2 are obtained at the contact point between resistances R 1  and R 3  as well as the contact point between R 2  and R 4  each to be supplied to resistances R 5  and R 6 . Accordingly, -(V 1  + V/2) and -(V 2  - V/2) are drawn out at terminals 21 and 22 respectively. Furthermore, -V/2 and V/2 are drawn out at terminals T 11  and T 12  each. As a result, the voltage at terminals T 21  and T 22  become the voltage featuring the opposite phases to each other with the phase corresponding to the level of the control voltage supplied to terminal T 1 . As the output voltage contains no distortion, the phase shift output can be obtained with a large level.
